ZURICH, SWITZERLAND IMPLEMENTS FOR MOVING RAILWAY WAGON Application filed November 8, 1928, Seria1 No. 317,932, and in Switzerland June 26, 1928.

The present invention relates to a new and improved shunting lever to move wagons, trucks etc. running on rails.

Implements for movingrailway wagons,

5 i. e. pushing-jacks or shunting levers, are known having a slide adapted to be placed on a rail of the track and an operating lever having two arms of unequal length and adapted to displace a wheel of the wagon and hence the wagon itself, said lever being pivotally mounted on the slide. Such known implements are not as a rule free from obj ection because, after each operation, the implement did not remain at rest to be again moved to the wheel, but canted on the rails, so that quiet operation with due safeguarding of the edges of the locking flanges was not possible. According to the invention the displacing implement is also provided with a slide, a two-armed operating lever pivotally mounted thereon, and two stop-members of strong construction, say hardened steel. In the construction of the present invention, these stop member-s are of a particular form'and have a special position with relation 'to the axis of rotation of the operating lever, making possible a better reception of the strong counter pressure on the edges of the stop members so that the slide does not cant, as

heretofore, and wear of the edges is avoided.

To this end, the stop members are of trapezoidal cross section and their upper surfaces lie in a common horizontal plane receiving the counter pressure, while their rear surfaces which are perpendicular to the rails are at right angles to the upper surfaces. In this manner the counter pressure is transmitted to the rails without displacing lateral forces and canting moments. The point of pivotal 4o slide is situated between and above the stopmembers and is so related to the stop members that the vertical middle plane which passes through the axis of the operating lever and transmits the counter force lies parallel to the rear surfaces of thestop members. Practice has shown that this arrangement prevents canting of theslide when the latter is moved to or fro by the operating 5 lever and thus permits quiet operation and attachment of the operating lever to the illustrated is provided with a slide 1 which is placed on one of the rails J of the track on which the wagon to be moved stands. Turnably mounted on this slide 1 by means ofa bolt 2 is a U-shaped bearing 3. Pivotally mounted in the bearing on a horizontal pin 4 is a two-armed operating lever 5, one arm 6 of which is formed as a handle. The other, very short, arm 9 engages the rim of the wheel. Abutment pins 7 are provided on the slide 1 and limit the turning movement of the bearing 3. V

Removably mounted on the slide 1 are two stop-members 8 of hardened steel which are at right angles to the rail J and are secured in position as by means of cotter-pins. The rear surface of each stop member 8, is substantially perpendicular to the rail and the upper surfaces of the stop members are horizontal in one plane, that is, at right angles to Y 7 the rear surfaces. The construction and position of these stop-members is such that the rear surfaces of the front stop members are further away from the vertical middle plane passing through the pin 4, and in which the counter force falls, than the rear surfaces of the rear members 8 (see Fig. 2).

, What I wish to secure by U. S. Letters Patent, is v 3 V A device for moving railway cars, comprising a slide plate, a bracket therefor, a two armed lever, a horizontal shaft journalled in said bracket and about which said lever os-.

cillates, and two stop members trapezoidal in cross section and disposed transversely of the slide plate, the front member being positioned nearer the middle plane passing through the axis of rotation of said lever than the rear member, the upper surfaces of both members lying in a common horizontal plane and both rear surfaces of the top members being in vertical parallel planes.

In testimony whereof I aflix my signature.
